Investigators have ruled out one vehicle in the probe into the Jersey City hit-and-run death of a Japanese woman last week and today authorities released new, enhanced photographs of three vehicles they are currently trying to locate.

Initially the Hudson County Sheriff's Office had been looking at a red and silver chrome lunch truck as possibly being involved, but it now has been ruled out in the Feb. 20 death of Ayako Okabe, 30, on Routes 1&9, just north of Duncan Avenue.

Investigators are now seeking the public’s help in locating what is believed “to be a dark-colored, four-door car, a light colored full-size SUV and an 18-wheel car carrier truck with multiple lights, Sheriff Frank Schillari said today.

The photos, two of each vehicle, were taken from surveillance cameras in the area and have been enhanced, officials said.

At about 6:30 p.m. on Feb. 20, Okabe was riding her bicycle home after finishing her last day at work at a nearby shipping company when she was struck. Okabe, who had a degree in economics, died in the street.

Okabe was to fly home to her family yesterday. Instead, her grieving husband and two siblings flew to New Jersey to attend her cremation yesterday. They will carry her ashes home on a flight tomorrow.

Yesterday her husband, Yuto Iizuka, 33, said through a translator that when Okabe came to the United States "of course I was sad but I am the number one fan of her so I wanted her to make her effort to learn jazz."

Iizuka, who is an engineer, said “When I heard this bad news I felt I must go to U.S. to see my wife. She was in trouble so I needed to go to the U.S. to help her."

Anyone with information on the hit and run is asked to contact the sheriff's office at (201) 915-1300. Officials said all calls regarding this case will remain anonymous.
